“…In the view of diverse application arenas, the changes in polymer properties occur according to the types of fller materials and their utilization in order to obtain the desired strength and higher modulus [24]. Hence, a fbre reinforced polymers (FRP) are the type of composite prepared by using the polymers as a matrix material embedded with highstrength fbres [25,26].…”

The continuous demand of today’s scenario and ecological consciousness has made the researchers think about the utilization of alternate sources of materials without compromising the mechanical behavior and characteristics while focusing on the fulfillment of the desired requirements in the wide range of industrial applications. The present work is a noble attempt and a step towards the development of silk fibre composites (SFCs) reinforced with the vinyl ester matrix material. The processing and fabrication of SFRCs have been carried out using the traditional hand layup technique using untreated silk fibres (SFs) and silk cloths (SCs) in the form of single, double, and triple layers of SFs and SCs laminates oriented in uniaxial and biaxial directions. For the prepared composite samples, the density and void contents in the sample, mechanical characteristics in terms of their tensile and flexural strength, and tribological characteristics as well as the electrical impedance have been investigated. The percentage void content was found to be within the acceptance limit. The tensile and flexural test results show a considerable increment which indicates proper stress transfer from matrix phase to fibre with triple-layer cloths showing the highest tensile and flexural properties. In the tribological test, the coefficient of friction is higher in the case of cloth loading as fibre concentration increases significantly. In the impedance test, almost for all samples, the trend of change in conductivity with applied frequency is the same. From the economic perspective, the proposed composite is suitable for a wide range of applications in industries as well as this can be utilized as an alternate source of traditionally used floor tiles currently using ceramic materials. Also, the proposed composite has a biodegradable characteristic that is completely in accordance with the demand and consciousness involved in environmental and ecological perspectives.

“…MMT is used both as excipient and active substance in pharmaceutical products [24]. It has enhanced gel strength, mucoadhesive capability to cross the gastrointestinal barrier, and ability to adsorb bacterial and metabolic toxins such as steroidal metabolites [25]. A way to outspread the applications of clay-polymer nanocomposites with improved properties, is to modify polymers by incorporation of inorganic fillers [26].…”

In recent years, development of different types of nanocomposites have increased their utilization in the biomedical and pharmaceutical sciences. The nanometer size range and unique composition make nanocomposites a beneficial alternative to any single conventional material. The present chapter provides a general overview of nanocomposites, discusses different types of nanocomposites such as metal, ceramic and polymer nanocomposites. The discussion is further focused on different nanocomposite based controlled and targeted systems developed for delivery of various drugs including anti-cancer, anti-microbial, anti-inflammatory, anti-diabetic and cardiovascular drugs.

“…Polyvinyl alcohol (PVOH) also known as hydrolyzed ethylene-vinyl acetate is a promising example of biodegradable polymer matrix due to its unique properties such as water solubility, low toxicity, and film orientation characteristics 4,5 and the drawn film possesses high strength and modulus. 6 -8 The reason for this fact may account for the hydroxyl groups that produce more effective hydrogen bonding between the adjacent chains and consequently has a profound effect on the mechanical properties. 9 PVOH is also resistant to grease, oil, and solvent meeting the packaging requirement.…”

Composites consisting of a polymeric matrix and renewable resources have attracted scientific attention due to the idea of sustainable development. The objective of this study was to blend the polyvinyl alcohol (PVOH) and oil palm ashes (OPA) using solution casting approach. The results revealed that increasing the OPA loading in PVOH film would decrease both tensile strength and elongation at break of the blended films. The morphology of the tensile fractured surface was examined which supported the result obtained from tensile properties. Also, the thermal characteristics of PVOH/OPA films were studied. The glass transition temperature and crystallization temperature were increased when the OPA loading was increased. Thermogravimetric analysis indicated that the thermal stability of PVOH/OPA film was higher than the unfilled PVOH film.
